Improving the Accuracy of the Output Voltage of the Converter by Changing the Load Parameters

In the article on basis of theory invariance increase accuracy work system with converter for nuclear magnetic logging under condition change parameters loading is considered. Based proposed functional scheme two-channel control, formulas are given to determine structural relationships and internal influences control components reduce impact disturbances that occur both by changing load supply voltage. To maintain required value carrier voltage amplitude, it necessary reference or decrease amplitude sawtooth voltage, which equivalent increasing gain feedback circuit. this case, if you circuit, must ensure stability maintained. The implementation these proposals gives a more accurate formation bypass probing signal. provides realization regulation stabilization amplitude. paper considers various options reducing effect power perturbation output converter. By period operation generator, determined frequency voltage-controlled generator depends inverter, varies depending properties rock during logging, stabilizing probe signal increases. system, first channel in accordance second determining from phase detector, determines deviation real generator. application above techniques allows build circuit implementations transducers meet requirements
